Using Olympus MC-20 Teleconverter On Olympus 50-200mm F2.8-3.5 (Old Four Thirds DSLR Lens)

I did a fun experiment recently - I attached the Olympus MC-20 2X teleconverter on the old Four Thirds DSLR lens, Olympus 50-200mm F2.8-3.5. This combination officially is not compatible, but I managed to make it work. In order to attach the MC-20 Teleconverter, a compatible lens requires a receiving in to slot in a protruding part. The workaround was the Four Thirds to Micro Four Thirds adapter that has a hollow gap in it which allows the protruding part of MC-20 to fit in nicely. I technically had a 100-400mm F5.6-7 lens to work with, so I participated in a birding outing to Fraser's Hill organized by OM System Malaysia and YL Camera! The performance of this combo was a mixed bag, I did get some decent output which I am showing in this blog entry, but if you are serious about birding and wildlife photography, I'd say the glaring compromises are enough to point you to the other direction. I shared everything in my latest video here (click).
